Bill Clinton will moderate the opening session of the U.S.-Africa Business Forum, which Bloomberg Philanthropies and the Commerce Department are co-sponsoring in Washington on Aug. 5 — the middle day of a three-day U.S.-Africa Leaders Summit hosted by President Barack Obama.

The summit is expected to draw more than 40 African heads of state, the largest gathering of African leaders on U.S. soil — plus 200 U.S. and African CEOs, as well as Cabinet and congressional participants.

Former New York City Mayor Michael Bloomberg will introduce Obama for closing remarks. Vice President Joe Biden will also speak at the forum, to be held at the Mandarin Oriental hotel. Organizers say the forum is designed as “an opportunity for government and business leaders to come together to explore new investment possibilities that can fuel job creation in both the U.S. and African economies.”

Bloomberg, who has been active in Africa for more than 15 years, and Commerce Secretary Penny Pritzker will give opening remarks. Secretary of State Kerry, Treasury Secretary Jack Lew and World Bank President Jim Yong Kim will be among those giving welcoming remarks. Moderators will include National Security Adviser Susan Rice and Charlie Rose.

Pritzker said in a statement: “President Obama asked us to assemble CEOs from both Africa and the United States and African Heads of State to discuss ways to deepen commercial relationships and bolster the presence of U.S. companies in African markets. Through these partnerships, … businesses and entrepreneurs in both the U.S. and Africa can help us spur increased transatlantic U.S.-African growth and prosperity for decades to come.

“I especially want to thank Michael Bloomberg and Bloomberg Philanthropies for their partnership in this forum, and for their unwavering commitment to improving economic development, health and the environment across Africa.”
